What it the «CoinJoin»?
The mechanism by which several participants combine their coins (or, to be more precise, UTXO) into one large transaction with several inputs and several outputs. The observer cannot determine which output belongs to which input, as well as the participants themselves. This makes it difficult for third-party organizations to keep track of where a particular coin was received from and where it was sent to (unlike normal bitcoin transactions, where there is usually one sender and one recipient).
This can be done using non-storage software such as Wasabi, which eliminates the risk of extinction or theft of funds. Each of the signatures is created on the computers of the participants, so anyone who tries to connect the signatures cannot change the transaction or redirect funds. The funds will always be located at the Bitcoin address that you control.
This can be done in a decentralized way so that the service does not depend on external parties or centralized servers. It is simply necessary for the parties to the transaction.
CoinJoin can be applied several times, and since many transactions are grouped, participants can save on transaction fees. CoinJoin is the preferred method of gaining privacy on the Bitcoin network.
CoinJoin means: “when you want to complete a transaction, find someone else who also wants to complete the transaction and complete the joint transaction together.”
